Andrew, QuickMount PV has been amenable to building custom standoffs. They would be crazy expensive if you only needed a few but for a big job or multiple projects, they might be an option for you.
Also, for using galvanized rail you may want to check out Cooper B-Line's solar products. Their clamp system, coupled with the WEEB-WMC is ETL listed to UL 467. Though their published documentation isn't quite as clear, the guys you get on the phone say this is true with both their aluminum and galvanized steel channel. They also have told me they are working on UL 1703/2703 approval for their complete system. It was over a year ago when I talked to them. I have used a ton of their clamps. With certain modules they're wicked, my favorite clamps out there, beefy 5/16" hardware, they come pre-anti-seized, really nice units. With other modules the clamp seems to pull on the frame in just the wrong way, makes you a little nervous. Cheers, -Nathan -- Nathan J.

Dear All, While not participating much in the dialog I greatly appreciate your time and knowledge on matters of the Sun. My question is two fold. Are folks using galvanized or hot dipped galvanized in any way, shape or form out there for their mounting systems? I feel like I need to know this as we only use aluminum because our climate is so wet. Yet we are in a situation where using galvanized might be the best and only options, although we am not seeing anything with galvanized that is readily out there either. Fold Two: Does anyone know of a source for 'standoffs' that are greater than 7"s but less than say 20"? Sincerely, Andrew Koyaanisqatsi President Solar Energy Solutions, Inc.
